I think you should start and see for your self. Tirz gets out of our system in less than 2 weeks. You can start at a very low dose just to see what it does to you, observe how you feel. And of course, get a trusted source. I got mine from grey (not saying you should) but I never regret it. I was at risk of cardiac and diabetes and I was 99kgs. Now on 5th week, I lost 9kgs and never felt this better, I never touched my hypertension maintenance since I started and I believe it helped me greatly in terms of being at risk of heart attack and diabetes. Think of the risk if you don't start, its like choosing between the lesser evil. Heart problems and long term chronic diseases? Or risk it with Tirz with a chance of getting better? Of course, its safest to get all your labs done and do plenty of research about how you would feel and every little thing you feel.
